Application filed February 17, 1928. Serial No. 255,087.

The invention relates to staplingdevices. The object of the invention is to provide a stapling device more particularly designed to set and clinch staples securing the removable head to the siding of a container.

By the present invention one end of the "staple is driven into the fibre siding of the container while the other end of the staple is turned over a bead formed on the removable head of the container and driven into the librefor'minga part of-said head.

'fhe invention furtherconsists in the sev-, oral-features hereinafter set forth and more particularly defined by claims at the conclusion hereof. 1 r

, In thefdrawings Fig; '1 isa side elevation --"'vieW*of a device em y the invention part of one of the handles being broken away, the device being shown in its final position;

Fig.2 is'a'view similar to Fig. 1, parts being broken away and parts being shown in section, with the device inloading position-iii?"- Fig-'3 is a front elevation view of the device embodying the invention;

Fig. 4 is a detail sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a side elevation view of the staple upon which the tool acts.

Referring to the drawings, the numeralfi designates the body of the tool, which is provided with a longitudinally extending slot 7 which is open from its lower end to a bead engaging groove or hook portion 8 having a staple-bending-and-forming groove 9 therein.

A sliding member or plunger 10 is mounted to slidably reciprocate in the slot 7 and a longitudinally extending groove port on 11 alining with the groove 9 and merging into a staple-end-receiving pocket 12. The plunger 10 is reciprocated by means of a bifurcated head 13 whose bifurcations are formed into the shape of companion cams between which the plunger 10 is mounted and to which it is pivotally secured by a pin 14 passing through an opening in the plunger and set at its ends in the cams, said head being formed integral with or secured to a handle 15. Swinging of the handle 15 from the position shown in Fig. 2 to that shown in by the grooves 9, 11 and 12 a'nd' tlie 'dev is hooked over the beaded edge""17-*ofthe removable head 18 associated with the'sidin'g 19 of a container and the handle is'turned to move the plunger 10 upwardl the staple will be driven at its lower en 20*into the siding 19 of the container andthe pressure exerted longitudinally of the-staple by the plunger will, through the cooperation of the forming die 9, bend the upper end 21 of the staple over the bead and embed it into the top 18 of the head. As shown, the handle 15 swings toward the inside of the container in.afiixing the staple and inthis case the handle 22, aflixed to the top 6 and extending laterally therefrom, is pressed on by the operator while affixing the staple so as to secure an eflicient, embedded engagement of the lower end 20 of the staple with the siding. It is possible, of course, to reverse the position of the handle from that shown in Fig. 1 and in that way dispense with the handle 22, but in doing so such severe side-thrusts are created against the side of the container adjacent the portion being acted upon by the lower end of the staple that it tends to crush the siding of the container and, therefore, the handle 15 has been arranged as shown and associated with the handle 22.

It will be noted from Fig. 1 that the hook portion 8 fits over the head 17 formed on the head of,the container and that the ortion of the body adjacent the groove 11 epends from the side of the container so that the container forms a rest for the tool and interlocks therewith over the bead.

While the association of the staple with the particular type of container herein shown does not form a part of the present invention 95 which is directed to the tool, it will be note that by applying the staple in this way an efficient, locking connection is had between the body of the container and the removable head since the staple engages a reinforcing 100 head-band 23 and the lower pointed end 20 grips into the siding adjacent the lower edge of'a reinforcing metal mouthband 24 surrounding the siding of the container.

With a tool of the character above de- 105 scribed several staples may be driven into the siding and top of the container, suitably spaced about its periphery, and the cover therefore securel locked thereto.

I desire it to e understood that this in-
